Thank you so much for your reply. I followed your advice, and it works! I went through the manual, and a few introductory power point slides, included in the package. I was hoping to find examples to make sure my use (and interpretation) of the program and its output is correct. I noticed that there are some data files in the "Example" folder, but didn't find any document using these example data files in the package. I'm searching learning resources online, and would appreciate any further suggestion on this matter.
Thanks again for your kind help.
